Good luck!

[Update 8/31/07: Here's the answer:

These are horn weights for a bull. To keep bulls from seriously injuring each other when fighting, these weights were placed on the horns to make the ends point downward. They were also used to fix mismatched horns, where one horn grew slightly higher than the other. If a horn weight was left on for just a few weeks, it would easily change the higher horn's angle of growth. Modern versions can be seen here.
